Our GSHP has this. You set it up manually and adjust the heat curve until you obtain steady internal temps. How it technically does it I couldn't say for sure but it can see the outgoing and return temps on the UFH and knows the external temp. Ours will keep the house within 1 degree C unless I run the wood burner

Hi all. Not done much 'eco' work on the house for some years but now with sky high electricity costs interested in extra PV combined with battery storage plus an agile tariff. Going to have a look through old threads to learn more about the subject Thanks
